We can make subtitles for a movie on wikimedia commons TimedText namespace, but templates within the subtitle don't expand. So license templates don't work.
Example:
https://commons.wikimedia.org/wiki/TimedText:Knowledge_for_Everyone_(no_subtitles).webm.ja.srt
The reason is expected subtitle is surrounded with <pre> tags.
| Status | Subtype | Assigned | Task | ||
|---|---|---|---|---|---|
| Open | None | T78509 Templates on TimedText namespace of wikimedia commons don't expand | |||
| Open | None | T111651 Convert TimedText to make use of ContentHandler | |||
| Resolved | Reedy | T145732 TimedMediaHandler should not call Article::getContent() |
Note this is by design -- the subtitle pages do not contain wikitext, they contain SRT or WebVTT subtitles.
We might want to think about a more general system for appending doc subpages/MCR sections/something to such things though; several systems in MediaWiki do different approaches with Data: and Module: pages etc.
